EYEWITNESS
Archives, travellers, a newspaper sketch and a spade › what each witness shows, reported as reported
The Order’s own records mention the harbour chain in 1454, 1462 and 1475 (a chain of tree-trunks), and in 1476, when Grand Master d’Aubusson ordered “a chain of very good and thick iron” after the December flood. Bosio, the Order’s chronicler, credits de Lastic with fortifying the harbour “with towers and chains, for the safety of ships and sailors.” The chain’s existence rests on these documents.
Pieces of the medieval chain outlived the Order. The traveller Carlier recorded a piece lying on the site in 1579; the traveller Rottiers saw another fragment at the Great Hospital of the Knights in 1825, later transferred to Constantinople, where it is preserved today in the Istanbul Archaeological Museum.
Physical evidence confirms what the archives only describe. At the base of the Mole of the Mills, autumn 2006 excavation uncovered a massive ancient marble column re-used as a bollard, standing on a marble-paved platform and still scarred by the chain’s own abrasion marks — rare, tangible, in situ evidence for a mechanism otherwise known only from documents.
A different kind of eyewitness record survives for the Tower of Naillac: a sketch published in the Illustrated London News on 16 December 1856 depicted the tower’s partial collapse, shortly after the earthquake of 12 October and the gunpowder explosion of 6 November that year — the same catastrophe documented for the Palace of the Grand Master.
Medieval tradition placed the Colossus of Rhodes, the bronze statue of Helios, at the harbour mouth, on the rocky base at the tip of the east mole — where the Fort of St Nicholas stands today. Several serious modern scholars incline to that identification. No archaeological evidence confirms it, and this page treats it as a long-standing, respected hypothesis rather than a fact.
GALLEY SLAVE
Told by a chained rower › from the silver whistle to the lamp on the Tower of Naillac
Every galley has its masters, and I have learned them as a fisherman learns the winds. The Galley Master stays aft, at the back of the ship, with the captain, from whom he receives his orders. There are also two under-officers, one amidships and one at the prow. Both are armed with whips, with which they flog the naked bodies of the slaves. I will not tell you what that feels like. I will only tell you that a man learns very fast to row. When the captain gives the order to row, the Galley Master gives the signal with a silver whistle that hangs on a cord round his neck. The under-officers repeat it, and very soon all fifty oars strike the water as one. It is a pretty sound, that whistle, thin and bright as a bird. In the whole world it is the sound I hate the most.
We are six men chained to a bench, naked as we were born, one foot on the stretcher, the other lifted and placed against the bench in front of us. We support a vastly heavy oar with hands stretching our bodies backwards while our arms push the loom of the oar clear of the backs of those in front of us. The stretcher is the wooden brace where we push with our feet. The loom is the long inner part of the oar, the part that stays inside the ship. One oar, six men, and every one of us must move at exactly the same moment, or the oar will fight us. On my left sits one, on my right sits another one. We have no language in common except the rhythm. In, out. In, out. That is the only sentence we all speak.
We are rowing ten, twelve, even twenty hours at a stretch, without rest. The officers go around and put pieces of bread soaked in wine into the mouths of the wretched rowers to prevent them from fainting. I take the bread. Pride is a luxury for men who can afford it. If one falls exhausted he is flogged until dead and then thrown overboard. Today, in the afternoon, it happens to a man on the bench ahead of us. I do not look. I have learned not to look. Nobody cries out, because we do not have breath. My bench neighbor leans toward me, as far as the chain allows. “Count,” he whispers. “Count. As long as you are counting, you are alive.” So I count. One. Two. Three. It is dark when the galley returns. The lamp at the top of the Tower of Naillac is lit, and I see it swinging above the water like a small, kind star. I hear the chain rattle up behind us, and I smell flour from the windmills, and I know that I have lived through one more day.

Statement of significance
“a chain of very good and thick iron” (the Order’s Council, 1476, ordering the chain across the harbour mouth.)
The Military Harbour of the Knights (Mandraki) is the small, northern harbour of Rhodes town, and was, in antiquity and throughout the medieval period, the city’s enclosed military or ‘war-galley’ harbour. Its defensive alignment has remained essentially unchanged from the 7th-century early Byzantine fortress — which occupied the same south-west corner of the basin later built up as the Palace of the Grand Master — to the present day, making it one of the most continuously fortified maritime sites in the eastern Mediterranean.
Between the 14th and early 16th centuries, successive Grand Masters of the Knights Hospitaller — Hélion de Villeneuve, Dieudonné de Gozon, Philibert de Naillac, Jean de Lastic, Jacques de Milly, Raymond Zacosta and Pierre d’Aubusson — built and rebuilt the harbour’s moles, windmills, towers, a free-standing fort and a demountable iron chain across the harbour mouth, creating a purpose-built naval base for the Order’s fleet of galleys. The physical reality of that chain-closure system, previously known only from archival references, was confirmed by the 2006 discovery of its marble anchor-bollard, still scarred by the chain’s own abrasion marks, at the base of the Mole of the Mills.
The harbour’s later history includes both catastrophic loss and remarkable survival. The Tower of Naillac, once the dominant landmark of the medieval harbour, was seriously damaged by the earthquake of 12 October 1856 and the gunpowder explosion of 6 November 1856 — the same catastrophe that struck the Palace of the Grand Master — and was entirely demolished by 1863, a widely regretted loss. The Fort of St Nicholas, the Tower of Gallia and the surviving windmills, by contrast, endured into the modern era and, since Mandraki’s opening as Rhodes’ small-craft and yacht harbour following the 1948 transfer of the Dodecanese to Greece, remain among the most photographed and visited monuments in the Dodecanese.
This layered history gives Mandraki exceptional and unusually multi-dimensional significance: outstanding representativeness as the physical embodiment of the Hospitaller Order’s naval and defensive identity, complementing the governmental and charitable identities documented elsewhere in this series at the Palace of the Grand Master and the Great Hospital of the Knights; outstanding historical value spanning the ancient shipsheds, the long-debated Colossus tradition, and two centuries of named Grand Masters’ building campaigns; and exceptional interpretive potential as a harbour that remains in everyday public use rather than behind museum walls.
This significance must be assessed together with an honest, monument-by-monument acknowledgement of integrity: the Fort of St Nicholas, the Tower of Gallia and the windmills retain substantial authentic Hospitaller-period fabric, while the Tower of Naillac is a total, irrecoverable loss, known today only from images, descriptions and an archaeological footprint. Notwithstanding this qualification, the Military Harbour of the Knights remains a monument of International importance: an integral component, alongside the Palace of the Grand Master and the Great Hospital of the Knights, of the Outstanding Universal Value of the UNESCO-inscribed Medieval City of Rhodes under criteria (ii), (iv) and (v).
ΥΑ 23084/737/25-8-1948 — ΦΕΚ 10/23-9-1948 (Ministerial Decision declaring the monuments of the Medieval Town of Rhodes, including the Mandraki harbour fortifications — the Mole of the Mills, windmills, Tower of Gallia and Fort of St Nicholas — protected under Greek Archaeological Law; subsequently confirmed under Law 3028/2002 on the Protection of Antiquities and Cultural Heritage in General).

Criteria: (ii) the fortifications of Rhodes, built by the Order of St John, exerted a wide influence in the eastern Mediterranean; (iv) the Order’s Rhodian towns form an outstanding architectural ensemble illustrating a significant historical period; (v) the town is an important example of a traditional human settlement shaped by successive cultural layers. The Mandraki harbour fortifications form part of the fortified circuit cited in the property’s Statement of Outstanding Universal Value, alongside the Palace of the Grand Master and the Great Hospital of the Knights.
